CREA DDF MCP
Security checks for vulnerabilities and agentic risk
Overview
This skill is a documentation-only DDF MCP setup guide with expected credential configuration, but users should handle those credentials carefully.
Install/use this only if you intend to connect an MCP server to your DDF account. Treat DDF client secrets or passwords as sensitive: keep populated MCP configs out of source control and shared folders, restrict local file permissions, prefer a secret manager or runtime injection where available, and rotate credentials if they may have been exposed.
Vulnerability Patterns
- Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
- Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
- Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
- Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
- Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally

This markdown file directs the user to export DDF credentials into the runtime environment, which is a sensitive operation affecting secrets handling. The instructions provide no warning about protecting credentials, avoiding shell history leakage, or ensuring they are set only in the intended environment.
